C# - ItemCommand Event Doesn't Fire With The Repeater Control?
Feb 21, 2011
I am building a website whereby people, before checking out of the shopping cart (and transferring to the payment iframe) can select which items from the shopping cart list to delete. The results from the shopping card are listed in a Repeater control. There is a Button in the Repeater which deletes a record from the database (used LINQ to SQL to do that.)
THe problem is that the ItemCommand event doesn't fire when i click the button. I tried 'response.write(test)' and it still would not work. It is as if the repeater cannot interact with the commands. It does render the results tho.

My repeater is available in a user control and I added the user control as a web part to an existing webpartzone. I could see all rows in the repeater (along with buttons). Once I click the (any) button, it loses all the rows and itemcommand never fires. I am using ASP.NET 4.0
I've got a repeater that's used to display the output of a dynamic report that takes criteria from webcontrols on the page. Within the repeater's ItemDataBound method I'm adding controls (Linkbuttons for sorting by column values) dynamically to the header of the repeater based on values selected in a checkbox list and at this point setting the CommandArgument and CommandName properties of the linkbuttons.
The issue is that when the linkbuttons are clicked they don't fire the ItemCommand event although they are clearly being correctly created and added to the header (there is some additional code to set the cssClass, text etc. and this works as expected.) The first column header in the repeater is set in the markup and the itemcommand event fires correctly on this one only. When the other column headers are clicked the repeater rebinds as programmed, but the columns are not dynamically re-generated.

I have a page with a couple of RequiredFieldValidators, each in its own ValidationGroup. One of the RequiredFieldValidator controls is inside a Datalist and the submit button triggers the relevant DataList_ItemCommand. It works just dandy until I add the ValidationGroup to the button, at which point clicking on the button no longer fires the DataList_ItemCommand event. Here is the HTML
[Code]....
Note that the ValidationGroup name is there, and it is unique. No other ValidationGroups exist with that name. As it stands, this code does NOT fire the DataList_ItemCommand event, so no update occurs. However if I remove the ValidationGroup declaration from the Button control, the event fires properly.
i have a repeater with a button in the footer template which i want to be able to update any of the items that are added (update quantites/totals/delete the item). however the 'UpdateOrderDetails' event never fires when the button is clicked. here is the code within the repeater...
<ItemTemplate> <tr> <td> <asp:CheckBox ID="chkDelete" runat="server" /> <asp:HiddenField ID="hidProduct_Key" runat="server" /> </td> <td><asp:Literal ID="ltlProduct_Name" runat="server" /></td> <td><asp:Literal ID="ltlProductOption_Size" runat="server" /></td> <td><asp:Literal ID="ltlProductOption_Code" runat="server" /></td> <td><asp:TextBox ID="txtQuantity" runat="server" /></td> <td><asp:Literal ID="ltlItemPrice" runat="server" /></td> <td><asp:Literal ID="ltlLineTotal" runat="server" /></td> </tr> </ItemTemplate> <FooterTemplate> <asp:Panel ID="pnlFooter" runat="server" Visible="False"> <tr id="trTotalExVAT" runat="server"> <td colspan="6">Total (ex VAT)</td> <td><asp:Literal ID="ltlTotalExVAT" runat="server" /></td> </tr> <tr id="trVAT" runat="server"> <td colspan="6">VAT</td> <td><asp:Literal ID="ltlVAT" runat="server" /></td> </tr> <tr> <td colspan="5"> <asp:Button ID="btnUpdate" OnClick="UpdateOrderDetails" Text="Update" runat="server" /> </td> <td>Delivery</td> <td><asp:Literal ID="ltlDelivery" runat="server" /></td> </tr> <tr> <td colspan="6">Total</td> <td><asp:Literal ID="ltlTotal" runat="server" /></td> </tr> </asp:Panel> </table> </FooterTemplate> the 'updateorderdetails' event in code behind is here Public Sub UpdateOrderDetails(ByVal s As Object, ByVal e As RepeaterCommandEventArgs) For Each objRepeaterItem As RepeaterItem In rptOrderDetails.Items Select Case objRepeaterItem.ItemType Case ListItemType.AlternatingItem, ListItemType.Item Dim chkDelete As CheckBox = objRepeaterItem.FindControl("chkDelete") Dim hidProduct_Key As HiddenField = objRepeaterItem.FindControl("hidProduct_Key") Dim txtQuantity As TextBox = objRepeaterItem.FindControl("txtQuantity") ' check for deletion or update If chkDelete.Checked Then Me.Basket.RemoveProduct(hidProduct_Key.Value) Else ' check for update If IsNumeric(txtQuantity.Text) AndAlso CInt(txtQuantity.Text) >= 0 Then Me.Basket.Products(hidProduct_Key.Value).Quantity = txtQuantity.Text End If End If End Select Next ' update order details BindOrderDetails() End Sub but this procedure is never called when the button is clicked, so wondered what i need to do to get this working </textarea></p> <input type='hidden' name='ID[5]' value='49574' /> <input type='hidden' name='URL[5]' value='http://forums.asp.net/t/1522852.aspx' /> <input type='hidden' name='CAT[5]' value='Web Forms' /> <input type='hidden' name='BOARD[5]' value='microsoft' /> <input type='hidden' name='P_DATE[5]' value='Feb 07, 2010 06:01 AM' /> <input type='hidden' name='RANDOM[5]' value='OoKSV9VFH' /> <input type='hidden' name='REPLIES[5]' value='3' /> <input type='hidden' name='USER[5]' value='aziz' /> <p><input class=subject type='text' size='90' name='SUBJECT[5]' value='Web Forms :: ItemCommand not get fire of datalist in IE' /><select name='INDEXED[5]'><option value='1' selected>UPDATE</option><option value='2'>DELETE</option></select>Feb 07, 2010 06:01 AM - Replies: 3 CAT: Web Forms<a target=_blank href="http://forums.asp.net/t/1522852.aspx">View</a></p> <p> <textarea rows=10 cols=100 name='POST[5]' onfocus='setSelRange(this, 0, 0)'/>
I have imagebutton inside datalist.....the problem is that onclick event of serverside not get executed for only IE ..but its work fine for mozzila....i m not getting what wrong in this code.
switch(e.CommandName) { case "Edit": //make editTemplate div visible HtmlGenericControl divEditContact = (HtmlGenericControl)e.Item.FindControl ("divEditContact"); divEditContact.Visible = true; break; case "Update": Employee updateEmployee = new Employee { employeeName = txtName.Text: employeeEmail = txtEmail.Text: } updateEmployee = API.UpdateEmployee(updateEmployee); //display lblUpdateConfirm visible to True // so user sees this confirm messge in the newly updated ItemTemplate }
How can I access my lblUpdateConfirm and turn its Text state to visible from inside the ItemCommand, so that when the user sees the newly updated ITemTemplate, the label is showing the "Update Confirmed" message?
Why would a button inside a Repeater not fire the Repeater's ItemCommand event? Is there a way to force it to do so? ViewState is Enabled. zn the code below, btnApprove and btnDelete are the buttons in question:
I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.
So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.
I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.
I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.
I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
I have a gridview with a onrowdeleting="SellersGridView_RowsDeleting" switch. My method is:
[Code]....
Well, it seems that when I try to delete anything - nothing happens. I tried to change the first line to Response.Redirect("foo") just to check if the event itself is fired, and it turns out that it doesn't.
i have a JQuery ui dialog box that opens up as a contact form when a link is clicked, which works fine, my problem is trying to submit the information.
When you click the send button it fires a button click event of another asp:button ive got hidden on the page...
the post back event fires and the page reloads but the asp:button click event doesn't not fire?
I add linkbutton controls dynamically to a panel, this works fine, but I also add eventhandlers to them like this.. AddHandler mLink.Click, AddressOf mLink_OnClick But when I click the linkbutton links, the event never happend. I have one updatepanel wrapped around some panels. What could be wrong?
I have a multi view with 2 view in my page. when page is loading first view is set active. by click on a click I set active second view that contain AsyncFileUpload1. but UploadedComplete event doesn't fire. This control works outside of view correctly but into view doesn't work. I have to use multi view and this 2 view in my web page. what can I do?
MdsMenu:MenuItem is my custom WebControl. If I insert a Button control out of MdsMenu:MenuItem tag it works well but if I inserted it within MdsMenu:MenuItem tag it doesn't fire the concerned method. What's wrong with my code?

I have my ReorderList setup, and it seems to work. It doesn't give me any errors, and it allows drag/drop of the entries.
BUT, it never updates my datasource. I have tried putting breakpoints on the update events, both on the reorder list, but also on the datasource, none fires.
